Patented May s, 190e,

Application filed August 3, 1905. Serial No. 272,551.

To all 'La7/1,0m, t may concern:

.Be it known that I, WILLIAM BAKER WALKER, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Cans, Jars, &c., of which the following is a specication, reference being had to the accompanying drawings, forming a part hereof.

The improvement relates to cans, jars, bottles, &c., in which it is important and desirable that the contents be hermetically sealed and in many cases sterilized in order that the same may be kept for an indefinite time.

The object of the invention is to so construct a can, bottle, or jar as to permit of filling and then sealing against atmospheric infiuences by a movement of the stopper, which during the filling has been in such a position as to permit the final closure free from any contact with the outside air. This object is attained by constructing the can, jar, or bottle with a central tube through which the filling is edected and in which the stopper is retained during the filling and afterward moved to close the inlet and expel some of the fiuid, which acts as a seal against the air until the stopper is in final position.

The invention consists, essentially, in a bottle, can, or jar provided with a central tube having an inlet into the body of such jar, in combination with a cork or stopper movable within said tube and adapted to open or close said inlet, and also in combination therewith of means for moving said stopper, as hereinafter more fully described, orpointed out in the claims.

In the drawings, Figure l is a central vertical section of a can or jar embodying one form of applying the improvement, and Fig. 2 is a like section showing the invention applied in a different way.

In the drawings, 1 represents the can, bottle, or jar, which is provided with a central tube extending from the top to the bottom thereof and forming the mouth of the vessel at its upper end. This tube 2 has openings 3 3 at the terminus of the neck of the vessel, which form an inlet by which milk or other fluid may pass into the body of the vessel during the process of filling and pass out of it when the contents are needed for use and the vessel is to be emptied. The top of the tube or mouth of the vessel may be closed by a screw-threaded cap 4 or .by any other suitable means.

A stopper 5, proper size to fit the tube 2, is shown as having a washer 6 on each end, and a rod 7 screws through these washers and the stopper and may have a nut on the projecting end, if desired. The outer end of the rod 7 is provided with the ring 8 and has a stop 9 (shown in Fi l) and the equivalent of such stop. in the orm of a corner or shoulder 9 (shown in Fig. 2) of the dome, which allows the rod 7 to be operated by the ring 8 at the bottom instead of at the top of the can, jar, or vessel.

In either form the movement of the stopper to different positions within the tube is caused by moving the rod 7 u or down, according to whether the inlet formed by the openings 3 3 is to be opened or to be closed, the stop 9 ending the movement at the point of closure.

It will be apparent that, during the process of filling, milk or any other liquid product may be made to pass into the mouth of the vessel and through the inlet formed by the openings 3 3 and that after the vessel is filled above the level of the inlet the fluid in the neck of it will act as a liquid seal and exclude the air that may be above the stopper. When the stopper is pushed up to close the inlet, the surplus liquid will be ejected, and allair above it that might under different conditions enter the body of the vessel will be absolutely excluded from it. This liquid seal on the top of the stopper insures exclusion of the air and leaves the package hermetically sealed and ready for'steaming or sterilizing should it be desired to subject the contents to that process, as is frequently done.

These cans, jars, or bottles may be made of any suitable material; but 'aluminium is an excellent material for several purposes and uses to which thepackage may well be applied.

It is also to be observed that modifications may be made in the details of construction and mode or means of moving the stopper within the tube without in any way departing from the spirit or scope of the invention. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A jar, can or bottle, provided with a central tube, forming the mouth of the vessel and extending inwardly, said tube having an inlet to the body of the vessel, in combination with a stopper fitting said tube and adapted IOO IIO

to be moved below said inlet during filling and emptying and to be 'moved up and close said inlet when the vessel is filled7 substantially as described.

2. A jar, can or bottle provided with a central tube forming the mouth of the vessel and extending inwardly, said tube having an inlet to the body of the vessel, in combination with a stopper fitting said tube, and means for moving said stopper over and away 'from said inlet, substantially as described.

3. A jar, canor bottle provided with a central tube forming the mouth of the vessel and extending inwardly, said tube having an inlet to the body of the vessel, in combination z 5 WILLIAM BAKER WALKER.
